BRIQUE TING-IVIACHINE.

Specification of Letters Patent.

Patented May '7, 1907.

Application 6166 July 18, 1906. Serial in. 326,658.

1'0 all whom it may concern:

Be it known that 1, ROBERT SCHORR, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Briqueting-Machines, of which the following is a specification.

This invention relates to improvements in briqueting machines, the object of the invention being to provide a machine of large capacity in proportion to its weight and cost, one in which the movement of the compressing plungers shall be as short and slow as possible so as to reduce the amount of wear, one which will permit of forming briquets of any size or shape, and one in which all the parts will be readily accessible and in plain view of the operator.

In the accompanying drawings, Figure 1 is a broken vertical central section of the machine, certain parts being shown in side elevation; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Referring to the drawing, 1 indicates a vertical shaft having a step bearing 2, and upon said shaft is keyed, or it might revolve loosely thereon, a heavy bevel gear wheel 3 meshing with a bevel pinion 4 on a horizontal shaft 5 having a driving pulley 6 driven from any suitable source of power. Said wheel 3 has formed intergal therewith two concentric rings 7 8, the opposing vertical wall of which form, together with an annular bottom plate 9, an annular channel to receive the loose material, a mixture of raw fuel and binding substance, to be briqueted, said rings being connected to each other below said channel by radial ribs 10, the intervening spaces 11 between said ribs being large enough to permit the briquets to drop therethrough. The annular plate 9 is prevented from rotating with the wheel by means of a bracket 12 depending from horizontal beams 13. The material is fed into said annular channel immediately in front of said bracket, and is carried around with the wheel in the direction of the arrow, and as it is thus moved around is compressed by radial plungers 14, the inner ends of which extend through the inner wall of the ring 8, while their outer heads 15 abut against a crown cam 16 depending from an annular plate 17, supported upon posts 18. By means of said cam said plungers are slowly forced inward, causing the loose material to be pressed between the inner ends of said plungers and the outer ends of ejectors 19, which ejectors reciprocate radially through the inner ring 7, the openings for said ejectors in said ring forming the mold, and the inner ends of the ejectors carrying rollers 20 which at that time contact with the inner side of a crown cam 21 secured to a drum 22 depending from the horizontal beams 13, so that the ejectors are drawn inward at the same time that the plungers are forced inward. This part of the operation continues until the wheel has revolved through about one-fourth of a revolution, when the ejectors are no longer drawn inward, but are held against further inward movement by their rollers abutting against the outer side of a cam 23. The plungers 15 are then rapidly forced inward by the cam 16 for nearly one-fourth of a revolution, until finally a strong pressure is applied by the passage of the heads of the plungers against the periphery of a pressure wheel 24, which completes the compression of the briquets. The heads 15 at the outer ends of the plungers then pass into a cam groove 25, the inner wall 26 of which extends outward suflicient'ly far to completely withdraw the plungers. At the same time the ejectors move outward owing to the shape of the cam wall 23, so that each briquet in turn is forced out by its ejector into the space between the two rings, which is here not closed by the annular plate 9, so that the briquet falls through the aperture between the ribs on to abelt conveyer 27 by which it is conveyed to a distant point. Should. one or more of the briquets adhere to its seat upon the ejector it is forced off by the bracket 12. Waste material accumulating between the plungers is carried back to the feed position'by a narrow channel 29 formed between the inner wall of the outer ring and a wall 29.

The pressure wheel 24 revolves loosely upon a vertical shaft 30 hinged in bearings 31 and extended to act as a seat for a nest of springs 32, through which springs passes a tension rod 33 held in place by a collar 34 upon the upper bearing 35 of the main shaft. The object of this is to guard against overfeed or obstructions. pressure wheel will swing out and thus a thicker briquet will result.

I claim 1. In a briqueting machine, the combination of a revolving wheel having formed therein an annular channel into which the If either occurs, the

material to be briqueted is fed, a circular series of radial plungers reciprocating across said channel, a circular series of corresponding ejectors, moldsfor the respective plungers formed in the wheel on one side of said channel, means for successively moving each plunger across the channel, first, to compress the material in the mold, and then away from said mold and moving the ejector toward said channel to eject the briquet thereinto, and means for closing the bottom of the channel during the first part of the operation, while permitting the briquets to fall from said channel during the latter part thereof, substantially as described.

2. In a briqueting machine, the combination of a revolving wheel having formed therein an annular channel into which the material to be briqueted is fed, a circular series of radial plungers reciprocating across said'channel, a circular series of corresponding ejectors, molds for the respective plungers formed in the wheel on one side of said channel, means for successively moving each plunger across the channel, first, to compress 'the material in the mold, and then away from said mold and moving the ejector toward said channel to eject the briquet thereinto, and an annular plate covering the bottom of that portion of the channel in which the first part of the operation is performed, and cut away in the remaining portion of the channel to permit the briquets to fall therethrough, substantially as described.

3. in a briqueting machine, the combination of a revolving wheel having formed therein an annular channel into which the material to be briqueted is fed, acircular series of radial plungers reciprocating across said channel, a circular seriesof correspond ing ejectors, molds for the respective plungers formed in the wheel on one side of said channel, means for successively moving each plunger across the channel, first, to compress the material in the -mold, and then away from said mold and moving the ejector toward said channel to eject the briquet thereinto, an annular plate covering the bot- 7 tom of that portion of the channel in which the first part of the operation is performed, and cut away in the remaining portion of the channel to permit the briquets to fall therethrough, and a wall forming the side of a narrow channel for moving the surplus material to the point of feed, substantially as described.

4. In a briqueting machine, the combination of a revolving wheel having formed therein an annular channel into which the material to be briqueted is fed, a circular series of radial plungers reciprocating across said channel, a circular series of corresponding ejectors, molds for the respective lungers formed in the wheel on one side 0 said channel, means for successively moving each plunger across the channel, first, to compress the material in the mold, and then away from said mold and moving the ejector toward said channel to eject thebriquet thereinto, said means including a pressure wheel revolving against the ends of the plungers in succession to complete the pressure upon the briquet, and means for closing the bottom of the channel during the first part of the oper-- said channel, a circular series of corresponding ejectors, molds for the respective lungers formed in the wheel on one side oi said channel, means for successively moving each plunger across the channel, first, to compress the material in the mold, and then away from said mold and moving the ejector toward said channel to eject the briquet thereinto, said means including a yieldably supported pressure wheel revolving against the ends of the plungers in succession to complete the pressure upon the briquet, and means for closing the bottom of the channel during the first part of the operation, while permitting the briquets to fall from said channel during the latter part thereof, substantially as described.

6. A briqueting machine having a channel or groove into which the material to be briqueted is fed, a plunger moving transversely across said channel to compress the materal, one side of the channel being provided with a mold to receive the plunger, an ejector closing the other end of the mold, means for moving said plunger and ejector, first, to compress the material in the mold, and then to return the finished briquet to the channel, and means for advancing the briquet to the position of removal from said channel, substantially as described.

7. A briqueting machine having a horizon tal revoluble wheel formed with two concentric rings spaced to form an annular groove between them, radial plungers guided in said rings, and ribs connecting the rings below the lungers, and spaced from each other to form openings to permit the briquets' to pass therethrough, substantially as described.
